Men's Mentor Jacket

Style# 55103OR

Ruggedly designed, tested and constructed for ultimate storm-worthy protection in remote, big-mountain environments. The Mentor Jacket is a staple of the alpinist's quiver. The Mentor utilizes a blend of lightweight, waterproof, breathable 40D and durable 70D three-layer GORE-TEX® Pro. The design precisely targets high-wear areas with the 70D fabric -- like the hips and shoulders, places where a harness or pack often abrades the fabric—allowing us to shave weight in this fully featured alpine shell. The result is a racehorse with a workhorse pedigree: a lightweight, minimal and bombproof jacket offering reliable protection and technical performance in extreme conditions.

Workhorse (Review by Weixiao)

This jacket can take a beating for a shell. Pokes, stabs, abrasion.. it takes a lot to compromise its integrity. I've worked in this jacket for a year and a half in a full-body harness on rock, in trees, in rain sun and snow. Simple, functional and still in one piece.

My sizing; 5'9, 150 lbs. trim build wearing a men's medium.
Note I have room to layer underneath (base layer, mid-fleece and transcendent hoody for example). If you're looking to take advantage of the jackets trim fit, consult the sizing chart and make sure the jacket doesn't run short on you. Enjoy!

Great shell (Review by charles)

I love this shell! It does everything OR says it will and looks good doing it. I bought this jacket as a have around everyday because in SC in the summer you never know when its going to rain in a given day, but it will. It's also HOT and the full side zips are nice. I do a good bit of backpacking on weekends and this jacket is very light for its durability. This jacket seems to be able to do plenty more as my specific activities change over time because it seems like it is built to last a long time. The only slight drawback I have found, which seems strange to say because it is advertised as helmet compatable, is that if you aren't wearing a helmet there is a lot of extra material that cinches down well but could maybe be better. I'm also a large guy at 6'4" with long arms and being able to find a jacket that is long enough and covers everything (especially when raining) while not being bulky is a great find.

Great shell, plenty of features (Review by Sam)

I've used this jacket for the past two days skinning Saddleback in Maine, so I can't truthfully comment on long-term durability, but the features have been great thus far. I was looking for a waterproof shell with enough room to layer a fleece or insulated jacket, and this fits the bill despite being described as having a "trim" fit. It's nowhere near as trim as my old Arc'teryx Seeker Comp (Sidewinder) or the OR Lodestar, which has a VERY athletic fit. I've been using the Mentor in conjunction with a wool base and OR's Havoc hoody. After fifteen minutes of uphill, I've had to shed the Havoc, unzip the pits, and remove my helmet. The Mentor does a really nice job of venting, while still keeping you covered, especially with the high collar in front. The Mentor's hood fit perfectly over a Bern helmet during snow squalls.

Other things I like: the heavier denier nylon on the shoulders and waist - essentially where your pack straps and kidney belt make the most contact. It seems the jacket will hold up well when touring with a backpack.

One thing to note, should this be an issue for you, is that there's a lot of material in the sleeves. They feel pretty baggy, even with an insulated layer. No big deal so far. Separately, I recall a few reviews discussing snug armpits that restrict movement. This doesn't seem to be an issue with the 2013 Mentor. I'm a fairly slim 6'3", 175lbs, with a 34" sleeve length and I went with a medium, if that helps... definitely enough room in the pits and plenty of sleeve length.

HARD shell (Review by Hopper)

I have had a Mentor for 2.5 years. I have used it ice climbing, winter camping and backpacking. The full side zips are fantastic for ventilation and wearing a harness. The hood fits over a climbing helmet and adjusts well when not wearing a helmet. It is indeed completely water proof and bombproof. OR's infinite warranty is also great, although i would be surprised if I needed it with this one. The Mentor is well built. I would love to have another one!
